We are using ADM1278 hot swap controller in our server board schematic. PFA schematic page for reference. But due to the unavailability of ADM1278, we need to find an alternate. We are considering LTC4215 since it is in stock and has similar functionality.
However, in the datasheet of LTC4215 we could only find reference circuit for 16.6 A circuit breaker (page 24). Our application requires 140A current. Would it be possible to share a reference circuit for higher current using LTC4215? Also is it ok to use multiple FETs in parallel connected to GATE pin of hot swap controller to handle high current requirements?
Also, please let us know if any other suitable alternate is available for ADM1278.
